Inventor: DUBOTS DOMINIQUE
IPC: C01B31/36
Filed: 1989-11-07
Abstract: The invention relates to a process for the production of micron- sized  alpha  or  beta  silicon carbide powder by high temperature reaction of a source of silicon with a source of reactive carbon in the powder state. According to this process, the mixture of the silicon source, as a micron-sized powder, and the carbon source is reacted in a furnace whose heating zone is at a temperature of between 1500 and 2000 DEG C, in a stream of gas consisting of at least one constituent chosen from among nitrogen, hydrogen and carbon monoxide. The furnace temperature in the central heating zone is between 1700 and 2000 DEG C; the residence time of the mixture of silicon source and carbon source in this zone is at least 30 minutes.

Abstract: One or more processors (11a to 11c) for controlling machining stations having one or more shafts are arranged. The number of processors depends upon the constitution of the machine tool, and these processors are connected via first common bus (31) to a CRT and MDI unit (21), NC machining program supply means (22, 24), and programmable controller (23) that controls power sequence of the machine. These units are commonly used by the processors. Further, the processors (11a to 11c) are connected to shaft control units (41 a to 41 c) via a second common bus (51) so that each of the processors can exclusively use a predetermined shaft control unit through which the corresponding machining station is controlled.

Abstract: A numerical controller which controls multiple spindles through a plurality of channels (10, 20, 30). When the machining program of the first channel (10) is stopped in response to a single block signal (6), the machining programs of other channels (20,30) are placed under the feed-holding condition. This makes it possible to maintain synchronism in executing the whole machining program and to prevent the machining from losing balance and from interfering.

Abstract: Un système permet de détecter l'orientation angulaire relative de deux segments d'articulation relativement mobiles d'un corps vivant, réunis au niveau d'une jointure. Le système comprend au moins deux tringles (56 et 57) accouplées autour d'un axe de pivotement (100) de sorte que lesdites tringles (56 et 57) pivotent l'une par rapport à l'autre autour de l'axe (100) de manière à définir un angle mécanique variable entre lesdites tringles (56 et 57) autour de l'axe (100). Les deux tringles (56 et 57) sont fixées respectivement aux segments d'articulation (36) de sorte qu'elles pivotent autour de l'axe de pivotement (100) lorsque les segments d'articulation (36) pivotent autour de l'articulation. Un capteur à effet Hall (104) sert à détecter avec précision l'angle mécanique. L'angle mécanique détecté par le détecteur (104) est ensuite mis en corrélation avec l'angle réel formé par les segments d'articulation (36). Cet agencement s'utilise avec chaque articulation de doigt et de pouce de la main pour fournir des données représentatives des orientations des doigts (32) et du pouce (34) d'une main.

IPC: G11B7/09
Filed: 1989-07-13
Abstract: A method for compensating offset voltages selectively in a focusing circuit that focuses a beam from a source of light on a recording medium and in a tracking circuit that positions a beam of light on data storage tracks on a recording medium. A beam of light reflected from the recording medium is directed onto a photodetector which has a plurality of photodiodes. The difference of the output voltages from the photodiodes is taken for generating an error signal which is stored as a reference during a first stage in open or closed state of the circuit selected. The selected circuit is then closed and a compensation parameter is supplied in a second stage to controls in the selected circuit. The compensation parameter is then varied until the error signal is substantially equal to the stored reference. The compensation of the offset voltages is independent of the tracking circuit, and the offset voltages in the focusing circuit can be compensated when the tracking circuit is closed.

Toutefois, les bits de polarité n'influent pas sur la sortie de corrélation si la sortie logique provenant de la porte (19) est dans un état donné se produisant si les bits de masquage associés indiquent que la valeur de gradient au niveau de la position particulière de pixel ne dépasse pas certaines valeurs de seuil minimum.

Abstract: Machine for making ice-lollies on a small handicraft scale. The molds (3) for the ice-lollies are immersed in an unfreezable liquid contained in a tank (2) in heat-exchange relation with the evaporator (4) of a refrigerating unit (5,6,7). A circulating pump (10) circulates the cold unfreezable liquid in order to enhance the thermal exchange between a reservoir (8) of cold liquid and the freezing tank (2), through a flap valve (13). As soon as the ice-lolly mixture has frozen, a thermostat (20) disactivates the refrigerating unit (4,5,6,7) and stops the operation of the cold liquid circulating pump (10). Therefore, the cold liquid flows back into the cold liquid reservoir (8). On completion of this back-flow, a second circulating pump (16) is activated either manually or automatically to pump a hot liquid from a reservoir (9) having heating means (19), through the flap valve (13), into said tank (2) where ice-lollies have been formed, so as to cause said ice-lollies to be released from the molds (3). Thereafter, by disactivating the pump (16), the hot liquid is flowed back into its reservoir (9), and the cold liquid circulating pump (10) is re-started for a new ice-lolly making cycle.

Abstract: A flexural pivot is configured as a multi-piece device which is specifically configured to tolerate vibration and shock loading. The flex pivot described uses pre-formed unitary (one-piece) support structures (12, 14) which have integral undercut areas, diametrically opposed slots for flexural member (16, 18) placement and key ways and the like, and near net shape geometry. The flexural members (16, 18) are pre-brazed to facilitate the assembly process. The design of the pre-formed support structures eliminates brazed joints which are common locations of fracture due to vibration and shock loading, resulting in a significantly strengthened pivot. The overall configuration and method described provides an economical flex pivot, whereby the flex pivots are accessible for applications which have not heretofore been feasible.
